A diagnostic device is configured to capture diagnostic information about a subject (e.g., the subject's ears). The diagnostic device may include a diagnostic extension housing diagnostic elements (e.g., imaging chip, light sources, or lenses) and an ear canal engagement section coupled to the diagnostic extension. The ear canal engagement section may be shaped to position the diagnostic extension superiorly within the ear canal. For example, one side of the ear canal engagement section may be longer than another, which may enable the ear canal engagement section to contact the inferior wall of the ear canal for a longer distance than it contacts the superior wall. This configuration may allow more movement of the diagnostic extension when the device is inserted into the ear, which further improves the alignment of diagnostic elements with a desired area of the ear for diagnoses (e.g., the eardrum).

Those who suffer from eustachian tube dysfunction do not all experience symptoms continuously. The pressure of the middle ear may be normal most of the time, but temporary problems may arise at other times. Therefore, a tympanometry system is configured to monitor the functional acoustic characteristics of the ear drum as a function of time by measuring and monitoring the acoustic impedance of the ear drum as a function of time over a monitoring period based on a measurement sound signal emitted by a speaker (4) and a corresponding sound signal detected by a microphone (6). Display means (20') are configured to display the acoustic impedance or related acoustic quantity as a function of time. The system may further comprise storage means configured to store one or more target acoustic impedance as a function of time, and during the monitoring period compares the measured acoustic impedance with a corresponding target acoustic impedance, determines the difference (22) therebetween, and displays (20) and / or stores (30) said difference as a function of time on suitable display means (20') and / or in suitable storage means (30).

A head-worn sound reproduction device is provided in the form of left and right earphones, which can either be clipped to each ear or mounted on other headgear. The earphones deliver high fidelity audio to a user's eardrums from near-ear range, in a lightweight form factor that is fully “non-blocking” (allows coupling in and natural hearing of ambient sound). Each earphone has a woofer component that produces bass frequencies, and a tweeter component that produces treble frequencies. The woofer outputs the bass frequencies from a position close to the ear canal, while the tweeter outputs treble frequencies from a position that is either close to the ear canal or further away. In certain embodiments, the tweeter is significantly further from the ear canal than the woofer, leading to a more expansive perceived “sound stage”, but still with a “pure” listening experience.
